On a swell of ground, in the wild country extending from Bombay to the foot of the Ghauts, stood a small camp. In the centre was a large pavilion; the residence, for the time, of Major Lindsay, an officer whose charge was to keep the peace in the district. It was no easy matter. The inhabitants, wild and lawless, lived in small villages scattered about the rough country, for the most part covered with forest, and subject to depredations by the robber bands who had their strongholds among the hills. Major Lindsay had with him a party of twenty troopers, not for defence–there was little fear of attack by the natives of the Concan–but to add to his authority, to aid in the collection of the small tax paid by each community, and to deter the mountain robbers from descending on to the plain. He generally spent the cool season in going his rounds while, during the hot weather, his headquarters were at Bombay.

In England, retired marine Harry Brown spends his lonely life between the hospital, where his beloved wife Kath is terminally ill, and playing chess with his only friend Leonard Attwell in the Barge pub owned by Sid Rourke. After the death of Kath, Len tells his grieving friend that the local gang is harassing him and he is carrying an old bayonet for self-defense; the widower suggests him to go to the police. When Len is beaten, then stabbed to death in an underground passage, Inspector Alice Frampton and her partner Sergeant Terry Hicock are sent to investigate. They pay Harry a visit but don't have good news; the police have not found any other evidence, other than the bayonet, in order to arrest the hoodlums.

A policeman who is a patient at a hospital in Stockholm is brutally murdered, stabbed repeatedly with a bayonet. The investigation that follows is led by Martin Beck and Einar Rönn. It turns out that the murdered man had sadistic tendencies and was known among his colleagues for abusing his police privileges and brutalizing civilians. Although his colleagues had been aware of his behaviour, the police force's esprit de corps had suppressed complaints about him and prevented any reprisals…

The timeless techniques of the infantryman are demonstrated in this classic manual of hand-to-hand combat, which teaches soldiers how to win fights using bayonet fencing, knife fighting, jiu-jitsu, savate and boxing.
